Abstract: Low serum osteocalcin is a risk factor for type 2 diabetes mellitus (T2DM), and osteocalcin (OCN) release from bone is associated with an acute stress response. Both T2DM and stress are associated with depression. Here, a depressive episode was not associated with OCN concentrations among people with T2DM; however, higher concentrations of carboxylated OCN (cOCN) were associated with higher perceived stress among participants with depression (r=0.546, p=0.013) and T2DM. Controlling for age, sex, body mass index, glycemic control (HbA1c), insulin resistance (homeostatic model), depression, and antidepressant use, carboxylated OCN was associated with perceived stress (F=9.602, p=0.003), and this relationship was stronger in those with depression (depression × cOCN interaction F=4.702, p=0.033). The results identify circulating OCN as a neuroendocrine marker associated with chronic stress among people with T2DM experiencing a depressive episode.
